yeah I pulled over and took a picture 
On October 19th my '04 Tuono uneventfully clicked 50,000 miles.All relatively trouble free.I have had little problems but it's never failed to start or get me where I'm going.I'll list the mods and issues so you can consider if they'd be a deal killer for you.I had friends tell me that it would be like the Italian bikes of the past,unreliable,cranky and allergic to rain.Well not true.In fact I was testing my Darien on the way to work yesterday by running 100 MPH in the rain on route 70.No problem including the 'Stitch. (it was also the ony bike in the lot.I work at a Harley dealership!)

So if you're considering an Aprilia just buy it and ride it.I feel at this point 100K is a given,in fact it'll probably see more before it requires any significant attention.
Modifications
1.)K&N filter in a stock airbox
2.)Aprilia slip-on with corresponding Aprilia chip
3.)Sargent world sport seat-an absolute necessity!
4.)16/42 gearing-17/42 stock
Problems
1.)Fuel light died at 6 months or so-haven't missed it
2.)Turn signal switch at 1 1/2 years-Replaced under warranty no questions asked
3.)Sprocket carrier bearing went south at 44K-found at a bearing house for $24 each.I replaced them both cause if one went the other is gonna follow.
4.)The one way valve for the fuel tank vent (damn California plumbing!) malfunctioned caused the tank (plastic) to expand in the heat and crack the paint.Just unplugged the valve and all is well.This one kinda pissed me off but WTF.
If you've got any questions ask and I'll do my best to answer.I've got many,many miles under my belt on many bikes and this is the most versatile fun to ride bike I've owned.Commuter,back road bullet,track day weapon,touring it does it all without any fanfare.Just ask and it responds.
